Figure 6 is a side elevation showing the first step in opening the davenport, in ivliicli'tjhe back is folded down on the seat.

'lnftlre drawing the same reference characters are used to denote similar parts as described in our c'o'qaencling application, hereinbetore referred to, the natural se- .qu ncebr' order tollowing'for the new parts herein described.

- The stationary structure (1) comprises a base frame member (2), a back frame member (4-), upholstered seat (5), end arms (6 and legs upon which said base frame is mounted.

Loose seat cushions (7 are placed on theseat (5) when th'e bed davenport is used as a couch. An upholstered back (8) includes a lran'ie (9) to the corners of Which frame are screwed metal flanges (47) and respectively, each of said flanges havingpiifota-l' connections (39) and (46) with iperatin'g links a-ndbars the upper flange {47), asin Figures 1 and 4, being pivbtally connected through the medium'oi an adgusta-ble supporting leg by pins (46) and to theope'rating link (43), the lower flange (40) pi'votally connecting the operating bar by a pin (39) and also fastened with the lever (43) by a pin (42) at the branch terminal (41) of the operating- The lower end of operating bar (34) is n'iade in the form of a T head, into which is centrally apertured a square slot (48) andiii the extremities of said T are holes whiclrare adaptable to engage the springs (36) whose actions are equal and opposite indirection, the forward end oi one spring being connected at (16) to the rear end '01"- the opp'osit'e acting spring be;

ing connected at ('38) to the inside of the a connecting link Transversely connecting the operating n'iechanisin is a shaft (49) which is journaledon the cross bar of the frame, having square ends, 'Whiclrare wviedged into the square slot in the T headportion o'f"operati-ng bar (34) and holds the upholstered back (8) in balance,'while theop'eratin-g bar (34') is rotated on shaft (49) as a pivot when the bed da'ven'por't converted from a co'ucli'to a bed position; An' L1p'hol'ster'e cl*'stjrip*(29) projects forwarchfroin the upper edge of the back i'rame (4) and extends over the rear upper edge of the back (8) when foldedgthus giving the upper rear edge of the bed daveiiport a neat finish. lVhen the back (8) is folded as shown in Figure'h't he operating levers (4-3) andadjustable legs are folded arid concealed along the end edges of theback frame The operation of converting the bed clavenport from a couch position as shown in Figure l to that or a bed "position as shown in Figures '2 and 8 con-sists'ott grasping'thenpp'er portion of the back (8) and gently tipping it forward Ffrorna slightly inclined position to a vertical position and folding the saine'pver "until it rests upon seat (5), as shown in Figifi, it'bein-g gui-ded in this movement by the levers (43), r'evolvable about pins (42) awn-axis, This brings the web band (50) into view. he fingers are then placed beneath the Web band ('50) and a gentle pull is exertedtlrereon, causingthe operating bars (34) rigid With the rear of the same base frame'inernlo'er, by

transverse sha'it (49') to be swung forinside (it the front rail member (2) and the I wz'u'dly, this movement being assisted by the springs (36) exerting a pull due to the ten.- sion therein until the operating bar comes in a vertical or neutral position. As the bae is folded in a further direction until its face comes flush with the seat it does so practically due to its own weight, storing tension at the same time in the tension springs to be used again in converting the bed to a couch position.

Dur ng the final rotation of the back (8) from its ,neutral or vertical position to that of being flush with the seat (5) in the down position, the links (43), by means of pins automatically force the adjustable legs about the pins (46) as an axis from their folded position to that of an open position.

Throughout this movement of the rotation of the back (8) from an open posit-ion in bed form until closed position in a couch form, the same method of operation is necessary and the springs function in like manner, so that the conversion of the bed davenport from one use to another is practically automatic, due to the equal action and reaction of the tension in the springs.

lVhen the back is folded, the loose cushions (7) are placed on the seat to be sat upon, thus making it unnecessary to upholster the face (30) of the seat, which is used for sleeping purposes upon the removal of the cushions and unfolding the back The outside face (31) of the back (8) is upholstered, so that one may recline against the same while sitting on the davenport when folded as a couch. The inside or rear face (32) of the back is not upholstered and is used for sleeping when the back is let down to convert the bed davenport into a bed.

The upholstery of the seat (5) and back (8) may be provided with the best mattress springs.

It will be noted that there are few operating parts entering into the mechanical con struction of this bed davenport, those parts being simple and-not liable to get out of order. They operate easily and efliciently and are cheap to manufacture.

The easy and-automatic adjustability of all the parts in general, requiring little effort in the conversion from one position to another, the simplicity of all co-functioning parts, are exhibiting factors which make this device an article worth while.
